Night trains are very popular and have limited capacity so most summer dates are sold out.

There are only seats available on 15th July between Zurich and Lesce Bled/Ljubljana : 2 x 13.20€ through tickets.oebb.at. Add Eurail as a discount and select one-way tickets

Alternatives : 

- daytime train

- Nightjet to Graz : seats or couchettes in a lady compartment only

- 2 night trains to Vienna (through tickets.oebb.at) : seats, couchettes and sleepers available. Then train to Villach (departure 08:18) and Lesce Bled/Ljubljana -> second pass day needed (or you buy regular tickets)

In any case book night trains ASAP

Thank you so much!

I booked the train for 2 x 13.20€ through tickets.oebb.

Am I correct to say that I can get on the train with the PDF ticket and my Eurail App to show my Eurail pass ? No need to add a ticket manually into my Eurail App?

Seat reservations are indeed completely separate. You need to add any train you'd like to take to the app : whether it requires seat reservations or not. This gives you a QR-code (your ticket).

For night trains it can be a good idea to print seat reservations because the attendant might want to keep it.

Enjoy your trip ! :)
